Answer:

The vertex or top is ( 2, -9)

Step-by-step explanation:

Given y = (x - 5 ) * ( x + 1 )

x² - 4x - 5

See attachment.

The vertex of the parabola is the Top.

The vertex of a parabola is the point where the parabola crosses its axis of symmetry.

If the coefficient of the x² term is positive, the vertex will be the lowest point on the graph, the point at the bottom of the “ U ”-shape. If the coefficient of the x² term is negative, the vertex will be the highest point on the graph, the point at the top of the “ U ”-shape.

The standard equation of a parabola is it

y = ax² + bx + c.

But the equation for a parabola can also be written in "vertex form": y = a(x−h)² + k

In this equation, the vertex of the parabola is the point (h,k) = (2, -9)

Answer:

Answer: (12,0)


Steps:

First, put the equation in slope-intercept form.

y=mx+b

1.5x + 4.5y =18

Subtract 1.5x from both sides.

4.5y =-1.5x +18

Divide both sides by 4.5 to isolate y.

y = -1/3x + 4


Then replace y with 0 because the point for the x-intercept is exactly on the x-axis so the y=0.

0 = -1/3x + 4

Subtract 4 from both sides

-4 = -1/3x

Divide both sides by -1/3 to isolate the x

Pls help, and hurry. i will give anyone brainliest if you give the correct answer.
Anna11 [10]

Answer:

Two answers:

22 ≥ v

OR

v ≤ 22

Step-by-step explanation:

It's the same as solving for a variable in an equality. Imagine it as 17 = v - 5 for a moment. Simplify by subtracting 5 from both sides and re-add the inequality sign. This can be easily done since we are not multiplying or dividing, just adding and subtracting.
